Elecrow ThinkNode M6 Solar Node

The ThinkNode M6 Outdoor Solar Powered Node is a high-performance Meshtastic IoT device designed for harsh outdoor environments and industrial scenarios.

It features the nRFLR1262 LoRa transceiver module and the nRF52840 core processor, supporting Bluetooth and LoRa dual-mode connectivity to ensure stable signal coverage. Equipped with a 6W solar charger and two 18650 batteries, it offers all-weather operation. Its IP65 waterproof housing allows operation in extreme environments ranging from -20°C to 60°C. It offers flexible mounting options with a included wall mount.

ThinkNode M6 comes with dual SP11 waterproof aviation connectors and supports long-range communication, precise positioning, and low-power operation. It can be used out-of-the-box, and rapidly deployed, ideal for Meshtastic network expansion, remote monitoring, outdoor emergency response, and off-grid communications, especially in remote areas with limited outdoor network access.

SP11 waterproof connectors can be used for UART and I2C connected sensors.
